# Multi-source IP reputation with one combined authority...

`GET /api/security/ip-reputation`

## Request

- Base URL: `https://2s.io`
- URL: `https://2s.io/api/security/ip-reputation`
- Auth: API key in header `PAYMENT-SIGNATURE`

Multi-source IP reputation with one combined authority score (0-100). Polls four independent reputation sources in parallel and blends them: AbuseIPDB (crowd-sourced abuse confidence), abuse.ch threat-lists (Feodo botnet C2 + ThreatFox + Spamhaus DROP + Tor exit nodes), blocklist.de (fail2ban attack-report network), and StopForumSpam. Returns combinedScore, a verdict (clean / low / suspicious / malicious), which sources flagged it, per-source opinions (score + weight + detail), and enrichment (ISP, usage type, country, ASN, Tor). An authoritative threat-list hit (botnet/malware/hijacked netblock) hard-floors the verdict at malicious. Per-source isolation: a down feed degrades that opinion only. The one-call answer for 'should I trust this IP?' instead of trusting a single feed.

## Query parameters

- `ip` string, required
- `trial` 1

## Other responses

- `200` (unresolved $ref)
- `400`: Invalid request — not charged. error.code: BAD_REQUEST or INVALID_PARAM (parameter validation; error.details.issues lists each problem), MALFORMED_JSON, or a request-specific code. Other client errors: 405 METHOD_NOT_ALLOWED (wrong verb; see the Allow header), 413 PAYLOAD_TOO_LARGE.
- `402`: Payment required. Body is the x402 PaymentRequirements envelope with a multi-network accepts array; the per-call price is in accepts[].amount (and on the operation as x-2s-price). Sign for whichever rail you hold USDC on (EIP-3009 for Base, partial SPL transfer for Solana) and retry with the PAYMENT-SIGNATURE header (X-PAYMENT also accepted for v1 clients). Also PAYMENT_SETTLE_FAILED (error envelope) when a verified payment failed to settle: error.details.chargeStatus is "not_charged" (retry with a fresh payment) or "unknown" (the authorization may still settle before its deadline — check it before retrying).
- `429`: Too many requests — RATE_LIMITED: our per-IP / per-payer limiter. Not charged; retry after Retry-After.
- `5XX`: Server-side failure. 500 INTERNAL: unexpected error; quote error.errorId (also the X-2s-Error-Id header). 502 UPSTREAM_UNAVAILABLE (or another UPSTREAM_* code): the data provider failed — composite endpoints refuse unbilled when every source fails. 503 SERVICE_PAUSED: endpoint paused by the operator kill switch, retry after Retry-After; 503 SPEND_CAP: daily upstream budget exhausted. 504 UPSTREAM_TIMEOUT. Not charged.
